Unlock reliable fuelling for high power and ethanol builds with the Fuel-It S58 Port Injection Kit, available from Nforcd. Designed specifically for BMW models running the S58 engine, this aftermarket port fuel injection upgrade adds six supplementary low-pressure injectors to support big-power setups, high ethanol content such as E85, and demanding track or road applications. It is a plug-and-play solution with CNC machined, anodised components for long service life and dependable performance.

  • Dedicated S58 port fuel injection kit for BMW M2, M3, M4, X3M and X4M
  • Adds six supplemental injectors to support four-figure wheel horsepower builds with the right hardware and calibration
  • Compatible with pump fuel, race fuel, methanol and E85
  • CNC machined and anodised billet construction for durability
  • Works with stock fuel lines via included billet tee fitting
  • Made in the USA

What’s in the box

  • Fuel-It S58 billet fuel rail
  • Stainless steel braided fuel line with black nylon sheathing
  • Billet tee fitting for fuel supply compatible with factory fuel lines and compatible flex fuel setups
  • -6AN ORB fitting
  • -6AN ORB plug
  • Two 1/8 NPT plugs
  • Stainless steel mounting screws to secure the rail to the manifold
  • Injector installation jig and screw
  • 21/64 drill bit to open the factory injector bosses
  • Superlube

Recommended add-ons

  • Fuel injectors: Flow-matched DW or IDX 42 mm port injectors are available in 550 cc, 750 cc, 950 cc and 1050 cc sets. Injectors are required for the kit to function.
  • Port injection controller: A controller is required to run the additional injectors. Choose a BMS JB4 port injection controller when using a JB4, or a stand-alone controller for flash-only or factory ECU setups.
  • Flex fuel kit: For ethanol blends or E85, a flex fuel kit is strongly recommended to monitor real-time ethanol content and aid consistent tuning.
  • CAN-based sequential control: Optional CANfuel sequential controller enables ECU control of up to 8 injectors and supports inputs such as ethanol content, low fuel pressure, additional pressure sensors, EGT probes and external fuel pumps.
